just put a ball valve on the output of the return pump and dial it back that way...actually a bit of backpressure on a pump sometimes helps it be more quiet

+1 There are variable speed pumps available but are very expensive and not needed. As suggested, a ball valve on the discharge side of the return pump is the best way to go. Just don't restrict the intake side of the pump.
